[oi-dev] dmidecode package

[stes@PANDORA.BE]

Thanks that explains why kernel and utilities such as prtdiag seem to work fine.

$ ldd /usr/sbin/prtdiag 
        libsmbios.so.1 =>        /usr/lib/libsmbios.so.1

I suppose fixing DDU is low priority, I can certainly live with empty CPU info in DDU.

A nice project could indeed be modifying dmi_info to use libsmbios.

$ pkg search prtdiag
INDEX      ACTION VALUE            PACKAGE
basename   file   usr/sbin/prtdiag pkg:/SUNWcs at 0.5.11-2020.0.1.20570

Perhaps SUNWcs core system (Core Solaris) could deliver dmi_info ?

The DDU gui is nice and I was wondering where it gets its info from.

Thanks,
David Stes
